What effect does cutting threads have on PVC pipe?

Cutting threads into PVC pipe decreases its structural integrity, which directly impacts its ability to withstand stress and strain. When threads are cut, material is removed from the pipe, which can lead to weakened points that may fail under pressure or when subjected to movement or vibration. This is significant because PVC pipe is generally designed to maintain a certain level of strength across its entire surface area. The removal of material through threading compromises that strength, making the pipe more susceptible to cracking or breaking under extreme conditions. Additionally, threaded connections can create points of potential leakage, further diminishing the pipe's overall reliability in plumbing applications. Therefore, understanding the implications of thread cutting on PVC pipe is crucial for ensuring proper installation and maintenance of plumbing systems.
